The 243 heads with the titanium valve's were part of the LS6 engine. This was the standard engine on the Z06 Corvette and 04-05 CTS-V only. Other engines did in fact receive 243 heads, but never with the lighter valve's. They were exclusive to the LS6 package only.

The lighter valves are only offered in the LS6 specific engine packages. If you have some 243/799 heads off of a later model 5.3l motor they won't have the lighter valves. Also, the valves are sodium filled not titanium. Titanium valves only come in the new c6 z06 LS7 motors, if I am not mistaken.

ANYWAYS, just a quick Q- Let's sayfind some bare 243's for a decent price. How much does one expect to pay for a set of the LS6 hollow valves, not new? Do any shops have them after they do port work / valve jobs?
TSP? What do you guys do with the valves if the customer changes valve size?

Seriously, why make a comment like that? He made a mistake and said the wrong material, and later stated that he was wrong. I'd rather read terrible grammar every day of the week, rather than read all the disrespectful and douche bag comments that i see on here from random members... ON A DAILY BASIS.

I recently lucked into a set from a fella in Brick,NJ for $190 shipped. They
were new takeouts in a sealed bag marked Valvegod ?? (vendor ?)
check the classifieds I think Studderin is/was sellin' a new set also.

LS6 243 heads = hollow intake and sodium filled exhaust valves. All other 243 heads = solid valves. AFAIK the only way to tell for sure what you have is to weigh the valves... look here >>>> https://ls1tech.com/forums/generatio...ve-weight.html
